Hello guys,
I need help deciding if I should go for new PSU or stick with my old one from old computer, old one is pretty old. It is Corsair GS500 I googgled it and it first became avialable in 2011. So now I am really not sure if its good idea to put this old guy into my new built PC. Here are the spec:
Ryzen 5 3600
MSI b550 Bazooka
Kingston 16gb x 2 3200 MHz
Fractal design Meshtify
Samsung 970 evo 500gb

Going to use old GPU with this setup GTX 1060 6gb
I just need my CPU and RAMs for poker solving program

If you could please suggest me decent PSU would be very thankful!!
